How do you feel about the song? I personally feel like pop just doesn't fit DB. Pop music carries no weight, no epicness that stuff like a rock song or an epic orchestra piece can bring.
I just love Broly overall, he's just so chill in this one and his Ikari form is so cool and an impressive idea, representing the Super Saiyan 4 overall in Toriyama's writing, and the insane Broly added a sense of being scared, knowing that this psychotic killer will kill Goku no matter what, but when you watched the new one and saw this completely different Broly, you start to feel a sense of redemption for broly's change in writing.
